Root Growth and Productivity of Wheat, Chickpea and Potato as Influenced by Nutrient Management Practices

Abstract

Field experiments were conducted during rabi / winter (November-March) seasons of 2011-12 and 2012-13 at research farm of Indian Agricultural Research Institute, New Delhi to evaluate the root growth and performance of wheat, chickpea and potato grown in different soybean-based cropping systems with 5 nutrient management practices. The results revealed that root growth in terms of root length, root volume and root dry weight of wheat and chickpea were observed significantly maximum where 50% RDN was substituted with FYM along with 50% RDF. Whereas, all the root parameters of potato were higher with the fertilization of 100% RDF. All the yield parameters and yields of wheat in soybean-wheat-fallow and soybean-wheat-mungbean cropping system did not differ significantly. All the yield parameters viz., effective tillers m-2 , length of spike-1 , grains spike and 1000-grain weight as well grain and stover yields of wheat were highest with the application of 100% RDF during both the years. Similarly, the maximum values of yield attributes and tuber and haulms yields of potato were recorded with the 100% RDF during both the years. However, no significant variation among all sources of nutrient was noticed during 2011-12 and among 100% RDF and substitution of 50% RDN through FYM during 2012-13 in both the crops. Whereas, significantly maximum yield contributing parameters and grain and stover yields of chickpea were found in the treatment receiving 50% RDF+50% RDN through FYM followed by 25% RDF+50% RDN through FYM+ biofertilizers during both the years.

Impact of Organic Nutrient Management Practices on Yield Attributes, Yield and Economics of Wheat (Triticum aestivum L.)

“…with unsustainability issue in agriculture. Indiscriminate and continuous use of inorganic fertilizers has shown negative effect on physico-chemical and biological properties of soil, thereby affecting the crop productivity (Prajapat et al, 2016;Meena et al, 2018), besides causing environmental pollution (Virmani, 1994). The excessive use of pesticides also resulted in residues much above the safety levels and this brought to the attention of ill-effects of modern agriculture and paved the way for organic based farming which will not only give rich nutrients produce but also quality food devoid of any chemical residue (Mengi et al, 2016).…”

Effect of Organic and Inorganic Nitrogen Management and Planting Technique on Nutrient Uptake by Maize Crop

“…However, the exact structure can only be determined by laboratory analysis. In general, the nutritional quality of maize increases with the use of feed with a combination of organic and inorganic fertilizers [7]. Prajapati et al [7], from their research, reported that the highest nutrient uptake of N, P 2 O 5, and K 2 O was observed under treatment where integration of organic and inorganic source is applied i.e.…”

Gap Analysis and Economics of Front Line Demonstrations in Chickpea (Cicer arietinum L.) under Humid South Eastern Plain Zone of Rajasthan

“…This results indicated that higher average grain yield in demonstration plots compare to farmers' practice ascribed to the knowledge and adoption of improved technologies i. e. suitable high yielding varieties with more potential yield such as GNG-469 and GNG-663, timely sowing, seed treatment with fungicides and biofertilizers (Rhizobium PSB culture), use of balanced fertilization, timely weed management and need based plant protection measures. Prajapat et al (2016) yield enhancement, greater yield attributing characters and better root traits of chickpea due to application of recommended dose of fertilizers and biofertilizers. Likewise, yield enhancement in different chickpea varieties ascribed to phosphorus addition in vertisols (Neenu et al, 2014).…”
